CLARK EDWARDS, OF LISBON, NEW HAMPSHIRE.

STANCHEON.

SPECIFICATION forming part of Letters Patent No. 644,414, dated February27, 1900.

Application filed Cl'uly 28, 1899. Serial No. 725,375. (No model.)

T0 caf/ZZ whom t may concern:

Beit known that LCLARK EDWARDS,0 Lisbon, in the county of Grafton andState of New Hampshire, have invented certain new and usefulImprovements in Stanchions, of which the following is a specification.

This invention relates to stanchions and it consists in certain novelfeatures of construction and arrangement, which are hereinafter fullyset forth and claimed.

.Of the accompanying drawings, Figure l represents a front elevation ofa stanchion constructed in accordance with my invention. Fig. 2represents a similar view of the same in a reverse position and openedout. Fig. 3 represents an end view of the stanchion. y

The same reference charactersindicate the same parts in all the gures.

In the drawings, a and b designate theupper and lower supports, betweenwhich the stanchion c is swiveled, and d cil/designate IiXed beams, suchas the upright beams usually placed between adjacent stalls.

The stanchion comprises a frame consisting of the rigid portion,composed of the upper and lower cross-bars. c c2 and the connectingvertical bar c3, and the swinging portion or bar c4, pivoted at itslower end at e5 to the lower cross-bar c2 and constituting the fourthside of the rectangular frame. The frame is pivoted to its supports byswivelbolts ec.

When the stanchion is closed, the swinging bar c4 is in an uprightposition, as shown in full lines in Fig. l, and is then held by a catchf, pivoted at f to the upper cross-bar c and constructed as a loop,which normally passes around the end of the cross-bar c and confines theupper end of the swinging bar c4 in a recess c6, Fig. 3, .provided inthe end of said cross-bar. The catch rests in its normal position on apin f3, projecting from the side of the cross-bar. When it is desired toopen the stanchion and release the animal, the outer end of thecatchislifted and the swingbar allowed to fall away, as represented in brokenlines in Fig. 1. For convenience in manipulating the catch f one of itsends may, as shown, be extended to the rear of the pivot f' and turnedoutwardly to form a short handle f2. The upper end of the swing-bar c4is beveled on the inside, so that when replaced it will automaticallylift the catch f and become engaged therewith.

g g represent guiding and retaining arms for the swing-bar c4, said armsbeing pivoted at g at their upper ends -tol the end of the cross-bar c'and having a sliding connection with the swing-bar consisting of a ping2, joining the lower ends of the guiding-arms and passing through anelongated slot c7, formed in the swinging bar. To the upper end of theswing-bar is secured a U-shaped or forked member h, which I term a clampand which is adapted to engage one of the side uprights d d when thestanchion is open to prevent said stanchion from turning-on its pivot.The clamp 7i may conveniently be formed of a strip of sheet metal bentto shape and bolted to the swing-bar c4. When it is engaged with theupright, its arms embrace the sides of the upright. It has beencustomary heretofore in constructing stanchions to aix a fork or clampto one of the side uprights between the stalls or in an analogousposition, where the upper end of the swing-bar could engage it whenswung out; but by transferring the clamp from the Xed upright to theswing-bar I provide an arrangement in which the clamp forms less of anobstruction than heretofore, and, furthermore, I furnish areadily-reversible stanchion which can be employed to open toward eitherthe right-hand or the left-hand side of the stall Without necessitatingthe use of a second clamp. When the stanchion opens to the left, asrepresented in broken lines in Fig. l, its swing-bar becomes engagedthrough the clamp h with the upright d at the left of the stall, andwhen reversed so as to open to the right, as represented in Fig. 2, theswing-bar engages Vthe upright d at the right of the stall. Some personswill be enabled to operate the stanchion most conveniently opening tothe right and others opening to the left. versed from the position ofuse shown in Fig. l to that of Fig. 2, the catch f may also be reversedby taking out its pivot-bolt f and turning it over, so as to bring thehandle f2 to the front, or said catch may be provided When the stanchionis re-y IOO with a handle extension on both sides of the stanchion, soas not to require reversal, or the handle extension may be omittedaltogether without affecting the operativeness of the structure.

The side arms g act to steady and guide the swing-bar c4 and their novelmanner of attachment to the swing-bar by means of the slot c7 in thelatter and the pin g2, attached to said arms and traveling in the saidslot, affords a positive and simple connection, so constructed as toprevent the swing-bar from becoming separated from the guiding-arms.Owing to the fact that the arms g are permanently connected with theswing-bar c4, a1- though permitting the latter to swing owing to theslot-and-pin connection heretofore described, there is no possibility ofsaid arms g disengaging from the swing-bar c4 when the stanchion isswung around, so that the clamp h may engage either the beam dor thebeam d.

I claim- In a device of the character described, the stanehion-framecomprising upper and lower cross-bars the upper one having a recess inits end, a vertical bar connecting the ends of the cross-bars at oneside of the frame, a swing-bar pivotally connected to the other end ofthe lower cross-bar and having its upper end beveled 011 the inner sideand adapted to fit the recess inthe end of the upper crossbar, saidswing-bar being provided with an elongated slot c7, arms pivoted attheir upper ends to the upper part of the stanchion-frame and having apin at their lower ends occupying the said slot in the swing-bar, theforked clamp 7L secured to the upper end of the swingbar and adapted toengage either of two fixed uprights according as the stanehion isemployed as a right-hand-opening ora left-handopening stanchion, and aloop-shaped catch pivoted to the upper cross-bar and adapted to normallypass around and confine the upper end of the swing-bar in the recess ofthe upper cross-bar, said catch being adapted to be automatically liftedby the incline of the swing-bar when said swing-bar is being moved fromits outward to its inner position, and to then drop over and confine theupper end of said swing-bar in the recess of the upper cross-bar.

In testimony whereof I have afixed my signature in presence of twowitnesses.
